Sb掺杂TiO2光催化降解甲基橙反应研究

摘要

The degradation of methyl orange (MO) catalyzed by Sb doped TiO2 catalyst under UV-light was conducted. Catalyst preparing and catalysis degradation conditions such as Sb contenting in TiO2, calcining temperature and time,catalyst amount, H2O2 dosage, reaction time, light conditions effecting on the degradation ratio of MO has been investigated. The results show that, 5wt% Sb contenting in TiO2 showed good catalytic activity. Under optimum conditions, degradation ratio of MO can be up to 100% in 240 min.%考察了Sb参杂TiO2催化剂光催化降解甲基橙(MO)反应性能.研究了催化剂制备条件、Sb负载量、催化剂用量、H2 O2用量、反应时间、光照等实验条件对MO降解率的影响.实验结果表明,Sb负载量为5％的TiO2表现出了良好的催化活性.在优化条件下,反应240 min可将浓度为100 mg/L的MO完全降解.
